While searching the garage the other day for a baling hook, I found a box titled “old hearing aids.” I wondered how old some of these might be, and if there were any interesting features/design characteristics. And, why did I keep these? A number of photos of old hearing aids can be found in the literature, but usually don’t provide

In 1965, Harford and Barry were credited for the first accessible published description of across-head fitting1.  It was called the CROS (Contralateral Routing of Offside Signals).  Harford and Barry did acknowledge, however, that Wullstein and Wigand had published results on an almost identical across-head arrangement three years earlier2.  The Wullstein and Wigand work has seldom been quoted in related literature

This post is a continuation of an attempt to archive some historical events related to hearing aids – that of the auriculostomy.  As reported in a previous post, the auriculostomy may have been the first surgical involvement in the fitting of an electrical hearing aid.   It provided an alternate approach to the application of corrective amplification involving ear-level hearing aids

This post provides an historical archive to the application of hearing aids.  The auriculostomy may have been the first surgical hearing aid involvement in the fitting of amplification in that it provided an alternate approach to the application of corrective amplification involving ear-level hearing aids1.  This was in 1975.  It was an invention of Charles Strzalkowski, an innovative and creative

Hearing-impaired individuals, and especially older adults, find it difficult to perceive speech, especially in noise conditions.  Many turn to hearing aids to help resolve this difficulty. However, when they receive their programmed devices, the primary setting is for listening in quiet.   To help resolve this problem, most hearing aids today are programmed for different environmental listening conditions. It is

This post is a continuation of two previous posts relating to a proposed PSAP “Standard” (OTC Hearing Aid Standard, and PSAP Standard Review).  This post relates to a section of the proposed “Standard” relating to the “categorization of PSAPs” (personal sound amplification products).1     Categorization – Criteria for Standardization It is not clear what the purpose is for categories

Legislation recently passed in the U.S. House of Representatives1 and expected to be passed soon in the U.S. Senate2, requires the FDA to establish an OTC (over-the-counter) hearing aid category for adults with perceived mild-to-moderate hearing impairment, within three years. This category is estimated to overlap the hearing levels of approximately 60-80% of all hearing aids sold in the U.S. market

Both PCAST1 (President’s Council of Advisors on Science and Technology) and NAS2 (National Academies of Sciences) have recommended that OTC (over-the-counter) hearing aid sales be permitted for mild-to-moderate hearing losses. Additionally, the SB 9 Over-the-Counter Hearing Aid Act of 2016 introduced by Senators Warren and Grassley calls for the same.  These recommendations resulted from the identification of problems with the

On July 12th, 2017 the U.S. House of Representatives passed the FDA Reauthorization Act of 2017, which includes the Over-the-Counter Hearing Aid Act, and allows for hearing aid OTC sales.1    The Act creates a new class of over-the-counter hearing aids and allows non-prescription hearing devices to be marketed to treat mild-to-moderate hearing loss.  This bill is incorporated into the

by Matthew Bromwich, M.D.* Outreach work comes with many challenges, not the least of which is transportation of medical equipment. As an ENT surgeon, I travel with a portable audiometer. Typically, this device is a donated, tabletop, wired suitcase device with a handle. We have traveled to remote communities up north and to our outreach work in east Africa using
